SPI Ultrasound Physics Review Exam - Questions and Answers Relates to likelihood of harmful bio effects from cavitation Mechanical index Predicts maximum temperature increase Thermal index Measures output intensity of the beam Hydrophone Region of increased brightness due to higher intensities in focal zone Focal banding Occurs when sound travels through a medium with a lower attenuation rate than the surrounding tissue Enhancement Beam travels through an area of high attenuation Shadowing Bea...

Edelmen's SPI Exam Review Guaranteed Success What is the relationship between frequency and wavelength in ultrasound? ️️Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, enhancing resolution but reducing penetration depth. How does acoustic impedance affect ultrasound imaging? ️️Acoustic impedance is the resistance to sound wave transmission; differences in impedance between tissues cause reflections that form the ultrasound imag...
